l Claim.

This invention relates to improvements in devices for wheel suspension, and is divisional to my application bearing the Serial Number 167,- 001, filed October 7, 1937.

An object of the invention is to provide individual wheel suspension in a vehicle which will shift the center of gravity thereof when the same is making a turn in travel.

Another object of the invention is to provide improved wheel suspension throughout the vehicle which will be of such structure as greatly to improve and simplify the lubrication thereof.

Other and further objects of the invention will appear as the description proceeds, reference being had to the accompanying drawing, in which:

Fig. 1 is a plan View of an automobile frame and wheel suspension assembly embodying my invention.

Fig. 2 is a sectional View taken on line 2-2 of Fig. l.

Fig. 3 is a view on line 3-3 of Fig. 1.

Fig. 4 is a rear view in elevation of the rear wheel suspension assembly.

Fig` 5 is a view showing partly in elevation and partly in section the upper cam assembly employed in the device, and in elevation the lower cam assembly.

Referring more particularly to the drawing, the numeral Ill represents the conventional frame of a Vehicle. Attached to the side members thereof are the front suspension members I I and I2 which are inclined backwardly from the perpendicular.

Each front suspension member is comprised of an upper tubular member I5 secured as by the rivets I6 to the frame I0 and engaging slidingly therein the inner tubular member I'I. Afxed to the lower end of the inner tubular member II is a journal bearing I8 adapted to receive the front wheel axle I9 and having integral therewith the arm 20 adapted to connect at 2| thereof with a steering tie rod.

The upper and outer tubular member I5 has pivotally affixed at the top thereof the arm 22 which is adapted at 23 thereof to engage with a steering tie rod. A coiled compression spring 24 is held within the telescopng tubular members I5 and II. 'Ihe lower end, 25, of spring 24 is attached to the upper male cam 26. A complementary lower cam 2'! is cylindrical in form and is afxed by its lower edge 28 to the member I8. The upper end 29 of spring 24 is affixed to the lower member 30 of the top cam assembly which is completed by the inner member 3| which latter is surmounted by the valve housing 32.

A hydraulic shock-absorbing unit 33 is disposed interiorly of the coil spring 24, and is affixed to member I8 by a plurality of studs 34.

The upper end of the unit 33 is integral with the cam portion 3l. The unit 33 comprises a pair of telescoping tubes, 35 and 33, which serve also as an oil reservoir. A needle valve 31 communicates with and surmounts the upper and outer tube 35 of unit 33, and a spring loaded valve 38 is disposed in the bottom end portion of the lower and inner tube 3S. The structure of the rear wheel suspension is similar, but lacks the lower cam assembly present in the front units.

A pair of rods, 39 and 49, extend longitudinally of the vehicle, and are connected by the pairs of arms 4I and 42 to the upper front and rear cams, respectively, thus causing identical action of the top front and rear cams.

In use, the cams are so arranged in the front wheel suspension assemblies, that when the front wheels are turned in rounding a corner, the cams in the assembly on the inside of the turn will contract, whereas the cams on the opposite side will expand, thus raising that side of the vehicle.

It will be understood that the device is capable of many modifications in structure and design, without departing from the spirit of the invention, within the scope of the appended claim.

Having thus described my invention, what I claim and desire to secure by Letters Patent of the United States, is:

In a vehicle supported by steerable wheels at its front end, telescoping sleeve members connecting said Vehicle with the wheels, coil spring means within the sleeves to maintain them in extended relation, one of the said sleeves being turnable with the wheel as the latter is steered, an internally threaded flanged member xed to the top of the coil spring and connected to the other of said sleeves for axial nonrotating movement relative thereto, a worm cam engaged within said flanged member and adapted to extend the sleeve members relatively when it is moved in one direction and to telescope the sleeve members inwardly when it is moved oppositely, a cup member fixed to the lower end of the turnable sleeve, cam surfaces on the upper edges of said cup member, and a worm cam engaging said cam surfaces and connected to said turnable sleeve for axial non-rotating movement relative thereto, said worm cam being attached to the lower end of the coil spring and also adapted to extend the sleeve members relatively when it is moved in one direction and to telescope the sleeve members inwardly when it is moved oppositely against said cam surfaces, the cams and sleeves of one side of the vehicle being arranged to extend when the cams and sleeves of the other side of the vehicle telescope inwardly.
